I would take out some water, then add salt to that removed water to increase salinity.
For example if your tank is 200 gallons, take out 10 gallons and increase salt... If salinity is 1.023, then increase it to 1.026, mix and then re-add The above procedure probably will increase your salinity overall by .001 point, use your hydrometer or refractometer to test... Do this once a day until desired salinity is reached. You will probably need less salt added as you get closer to your optimal range, so just be careful. Once achieved, your salinity should stay at that, unless you have salt creep, just keep an eye on things and rub the salt creep back into the tank.

 ok befor you get carried away, you have to do a control first.. what you do is measure your Sg, ad a knowen amount of salt desolved in water then measure Sg to see how much it went up. what I recomend is to warm up some RO water.. add some salt and mix well (I would need to know the size of your tank and water volume to recomend a starting amount of salt) measure the Sg add the mixture in a high flow area wait 1 hour and measure Sg again. (this is based on a salt mix requiring 1/2 cup per gal) if you look at it another way 50 cups of salt will raise 100 gal .026, so 5 cups of salt will raise 100 gal of water aprox 0.0026, so 1 cup will raise 100 gal aprox 0.00052 10 gal aprox 0.0052 so if you have a 40 gal that is at 1.024 and you want to raise it to 1.026 you need to add about 16 cups of salt (double check my math befor following, its early and I am getting kids ready at the same time )Steve

Step 1
Take your hydrometer to one of 2 places. 1) LFS that has a refractometer and test its accuracy 2) Garbage can and buy a refractometer Make sure before you start making too many changes you get an accurate salinity measurement. Kevin

Another option would be to add a little salt to your makeup water everyday. That way the salinity will slowly rise.
